Listen: Fish Singing in Chorus Recorded

Scientists have found evidence that there are species of fish that sing in chorus at dawn and dusk, just like birds.
New Yorker’s Emily Anthes said that more than 800 species of fish are confirmed to create noises while some even shout which matches parts of the ocean that are loud.
"Clownfish chirp and pop by gnashing their teeth together. Oyster toadfish hum and blare like foghorns by quickly contracting muscles attached to their swim bladders. Croaking gourami make their signature noise by snapping the tendons of their pectoral fins," Anthes said.
While certain animals are known to produce sounds, fish seemed to be unlikely. Now, we have proof that fish also call to find mates, find food, and even solve territorial issues.
Robert McCauley from Curtin University in Western Australia and his team finished an 18-month study of fish noises in Port Headland’s coastal waters in Western Australia and were able to identify seven different choruses at both dawn and at dusk.
McCauley told Greta Keenan at New Scientist, "I’ve been listening to fish squawks, burble and pops for nearly 30 years now, and they still amaze me with their variety. We are only just beginning to appreciate the complexity involved, and still have only a crude idea of what is going on in the undersea acoustic environment."

Keenan said that the ‘foghorn’ sound is from a black jewfish (Protonibea diacanthus), while the grunting is from a species of Terapontid. The softer “ba-ba-ba” on the other hand is from a batfish.
With the use of two sea-noise loggers, the team was able to record the fish sounds. The loggers were located 21.5km apart. The seven fish choruses were recorded during late spring and early autumn.
